Thanks. I assume this is a new regression in next-20170906, since
you're responding to its announcement?

I don't quite see where the problem is yet (looking at next-20170906).
kernel/irq/msi.c includes linux/msi.h, which includes
arch/x86/include/asm/msi.h, which includes
arch/x86/include/asm/hw_irq.h and has a typedef for msi_alloc_info_t,
but I don't see any CONFIG_PCI guards there that would be relevant.
